Abstract
The utility model discloses one and cut rule, the lower center of centering cone is outstanding to taper off to a point, radially run through in centering cone side and through hole is set, one end of described expansion link is fixed on tip outside of sleeve Middle face, the other end inserts in this through hole, is provided with the retaining mechanism to expansion link on centering cone simultaneously.Tip coupling can be inserted in tip sleeve pipe in the utility model and also can slide, centering cone can realize being placed in cutting center of gravity, by means of gravity and the certralizing ability of centering cone, tip can circle by fast rotary, realize standard circular cutting, speed is fast, effective.Expansion link can regulate circular radius, practical.The utility model structure is very simple, but result of use is very good, easy processing and manufacturing, is applicable to promotion and implementation.
Description
Technical field
The utility model relates to the aid in Machining Technology field, is specifically related to a kind ofly cut rule for the circular cutting of auxiliary welding gun.
Background technology
In prior art, welding worker is welding round piece, or when needing to use flame cutter to cut out round piece, owing to there is no aid, workman first can only draw circular ancillary coil, then carrying out welding or cutting along ancillary coil with welding gun or cutting gun, if construction environment more complicated, workman can only lean on experience or eyes to estimate and operate.The utility model patent that publication number is CN203817585U provides a kind of electric welding to assist compasses, and its object just draws boost line before cutting, can not position and booster action in electric welding or cutting process to tip.All to there is precision low for various cutting mode above, and operating efficiency is not high, has a strong impact on the problems such as job schedule.
Utility model content
In order to overcome prior art deficiency, the utility model provides a kind of electric welding and assists compasses, and the utility model structure is simple, and discarded part can be adopted to carry out simpler production, but can realize the miscellaneous function of staff being justified to cutting or circle welding completely.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: one cuts rule, comprise tip sleeve pipe, expansion link and centering cone, the lower center center of described centering cone is outstanding to taper off to a point, and radially run through arranging through hole in centering cone side, one end of described expansion link is fixed on tip outside of sleeve Middle face, the other end inserts in this through hole, is provided with the retaining mechanism to expansion link on centering cone simultaneously.Described retaining mechanism arranges tapped blind hole downwards in centering cone upper end edge axle center, and tapped blind hole is communicated with described through hole, and in tapped blind hole, Matching installation has clamping screw, and clamping screw end is fixed with handle.Tip sleeve pipe is individual layer sleeve pipe, described tip sleeve pipe can also be arranged to inside and outside nested relationship, be slidably matched between internal and external casing.Or in tip sleeve pipe, bearing is installed.
Beneficial effect: tip coupling can be inserted in tip sleeve pipe in the utility model and also can slide, centering cone can realize being placed in cutting center of gravity, by means of gravity and the certralizing ability of centering cone, tip can circle by fast rotary, realize standard circular cutting, speed is fast, effective.Expansion link can regulate circular radius, practical.The utility model structure is very simple, but result of use is very good, and by probation dark in welder master worker favorable comment, easy processing and manufacturing, is applicable to promotion and implementation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the using state schematic diagram of Fig. 1;
Number in the figure 1 is centering cone, and 2 is tip sleeve pipe, and 3 is expansion link, and 4 is clamping screw, and 5 is handle, and 6 is welding gun, and 7 is tip.
Detailed description of the invention
Embodiment 1: one cuts rule, see Fig. 1, the lower center of centering cone 1 believes outstanding tapering off to a point, radially run through in centering cone 1 side and through hole is set, one end of described expansion link 3 is fixed in the middle part of tip 7 sleeve pipe 2 lateral surface, the other end inserts in this through hole, is provided with the retaining mechanism to expansion link 3 on centering cone 1 simultaneously.Retaining mechanism in Fig. 1 arranges tapped blind hole downwards in centering cone 1 upper end edge axle center, and tapped blind hole is communicated with described through hole, and in tapped blind hole, Matching installation has clamping screw 4, and clamping screw 4 end is fixed with handle 5.
See Fig. 2, in the present embodiment, tip sleeve pipe 2 is individual layer sleeve pipe, to be inserted by tip 7 in tip sleeve pipe 2 and to be slidably matched, with centering cone 1 for circle can move in a circle very soon.
Embodiment 2: on embodiment 1 basis, can also be arranged to inside and outside nested relationship by described tip sleeve pipe 2, be slidably matched between internal and external casing.
Embodiment 3: on embodiment 1 basis, be provided with bearing in tip sleeve pipe 2.
Claims (2)
1. one kind is cut rule, it is characterized in that: comprise tip sleeve pipe, expansion link and centering cone, the lower center of described centering cone is outstanding to taper off to a point, radially run through in centering cone side and through hole is set, one end of described expansion link is fixed on tip outside of sleeve Middle face, and the other end inserts in this through hole, is provided with the retaining mechanism to expansion link on centering cone simultaneously; Described tip sleeve pipe is arranged to inside and outside nested relationship, is slidably matched between internal and external casing, or in tip sleeve pipe, bearing is installed.
2. according to claim 1ly cut rule, it is characterized in that: described retaining mechanism arranges tapped blind hole downwards in centering cone upper end edge axle center, tapped blind hole is communicated with described through hole, and in tapped blind hole, Matching installation has clamping screw, and clamping screw end is fixed with handle.
